KNOCKDOWN HEATING APPARATUS FOR CORN-CRIBS.

Specification of Letters Patent.

Patented Apr. 16, 1912.

To all whom t may concern.'

Be it known that I, LOUIS C. EMMoNs, a citizen of the United States ofAmerica, and a resident of Cedar Falls, Blackhawk county, Iowa, haveinvented certain new and useful Improvements in Knockdown HeatingApparatus for Corn-Cribs, of which the following is a specification.

My invention relates to improvements in knock-down heating apparatus forcorncribs, and the object of my improvement is to provide a heatingdevice adapted for drying corn in a crib, and which is so constructed asto be easily separated and withdrawn therefrom, at times when it isdesired to remove the corn from the crib. This object I haveaccomplished by the means which are hereinafter described and claimed,and which are illustrated in the accompanying drawings, in which:

Figure 1 is a. perspective view of the interior of a corn crib, with myimproved knock-down heating or drying apparatus installed therein, partsbeing shown as broken away to bet-ter disclose the construct-ion of saidapparatus. Fig. 2 is4 an enlarged perspective detail of the mediallylocated cubical coupling of alined and communicating pipes. Fig. 3 is acentral longitudinal section of the coupling shown in Fig. 2. Fig. 4 isan enlarged detail view of the coupling used between the longitudinaland the transverse pipes. Fig. y5 is an enlarged perspective view of oneof the bracket-connections used to support transverse pipe-supportingbeams in said crib.

Similar numerals of reference designate corresponding parts throughoutthe several views.

Fig. 1 represents a corn-crib 30 constructed in the usual manner with aplank floor, uprights and horizont-al boarding secured on the saiduprights, the roof not being shown. At opposite ends of said buildingare boxes 28 and 29 respectively, covered and adapted to receive partsof the heating apparatus projecting thereinto for a purpose to behereinafter described and explained.

In communication with the box 28 is a tubular vertical boxing 19.rectangular in cross-section, which is closed at the top, and which isremovably secured to the outside of the crib by means of detachablefastenings, the nature of the latter being shown in Fig. 5. Each ofthese fastenings comprises a bracket plate 12, whose upper part 11 isoffset outwardly to space it apart suiiiciently from the crib upright towhich it is secured, and an angle-plate 13 14 whose part 14 is securedto the side of the boxing 19, with the part 13 received by the part. 11of said bracket detachably.

The outside of the crib is covered with paper or other suitable material31, adapted to close the openings between the crossboarding and theuprights, to retain and cause to rise the air heated in the building bymy heating device. The boxing 19 is separated from the interior of thecrib by means of a paper partition 33.

Lying adjacent to and placed longitudinally along the inner upper sideof the boxing 28 within the crib is a cross-beam 35, which is removablysupported in the proper place and height by means of brackets such ashave been shown in Fig. 5. Midway of the crib another cross-beam 34 isplaced on the floor, or may be supported similarly above the floor ifnecessary, and both the beams 34 and 35 serve as supports for thelongitudinally placed and alined pipes 1 2 of the heating device to holdthem in an inclined position, such pipes being inclined from the beam 35downwardly at a suitable degree toward the bottom of the boxing 29.There are several of these longitudinally alined pipes 1 2 placed in aparallel arrangement, each pipe 1 2 having its parts 1 and 2 lietachablyunit-ed by means of a coupling-block 3. Each coupling-block 3 has acentral longitudinal bore equal to that of the inner diameter of saidpipes, and the exteriorly threaded ends of the pipes 1 and 2 are iittedin the interiorly-threaded ends of the bore 7 of said coupling. Theoutside of said coupling is made rectangular to fit between the parallelupwardly directed ribs 4 of a base-plate 5, the latter having in itslateral ears openings 6, whereby it may be bolted to the cross-beam 34.The outer ends of each pipe 1 as also the outer end of each pipe 2, ismade to communicate witha cross tube made up of couplings and pipesections 10, 16 and l5, forming a gridiron shaped arrangement ofcommunicating pipes for general free circulation of a heated fluidtherethrough. In Fig. 4 is shown a corner coupling 10, in communicationwith the pipe 1 by means of a short exteriorly-threaded pipe-section 9,and a coupling-nut 8.

The intermediate pipe-sections 15 are connected by means of T-couplings16 with each other and with the abutting pipe 1 or 2 as the case may be.A cross-coupling 20 affords communication between the outer ends of thepipes 1 and the lower part of a boiler 22, by means of a connecting pipe21. A T-coupling 17 affords communication between the outer ends of thepipes 2 and a vertical pipe 18, the latter rising into the verticalboxing 19, and communicating by means of an elbow-coupling 27 with apipe 2G, the latter extending longitudinally across the upper part ofthe interior of the crib 30, but being inclined toward the coupling 27,with its other end passed through the wall of the crib andcommunicating?, with a coupling 25 and a vertical tube 23, the latteropening into the upper part of the boiler 22. The upper end of the tube23 above said coupling 25 is provided with an expansion receptacle 24;open at the top.

Tater heated in the boiler 22 rises through the tube 23 and flows intothe downwardly-inclined pipe 26 to the vertical pipe 18, whence the hotwater is distributed to the parallel inclined pipes 1-2 by means of thecross-connections above described, the water nally flowing back to theboiler through the pipe 21, the inclinations of the different pipes oftheapparatus aiding in the circulation. When the corn which may havebeen previously deposited upon said apparatus in said crib has beensufficiently dried by the radiant heat derived from the heatedcirculating water, the water may be withdrawn from the apparatus and theparts of the apparatus remo-ved from the crib to permit of the removalof the corn, in the following manner. The boxing 19 is lifted away fromthe crib, and then the horizontal boxes 28 and 29 withdrawn, the latternot being otherwise fastened to the crib. This exposes the couplings ofthe outer ends of the pipes 1 2 which lie without the crib, and saidcouplings may be easily removed from the pipes 1 2. Then by the use of apipe-wrench each pipe 1 and 2 may be turned so as to cause it to unscrewits inner end from the block-coupling- 3, when said pipes may be pulledout of the crib from under the superincumbent load of corn. The cornthen may be removed easily from the crib, and the rest of the apparatusremoved, if desired, The arrange ment of the parts of my said apparatusthus permits of the use of same without in- Copes of this patent may beobtained for convenience in the removal of the contents of a crib.

Having described my invention, what l claim as new, and desire to secureby Let ters Patent, is:

1. The combination with a repository and a boiler, of a plurality ofpipes in detachable communication with each other and with said boilerand located in said repository near the fioor thereof, the ends of thepipes extending outside of the repository, each pipe being composed oftwo alined sections, and fixed couplings adapted to detachably join thesections of said pipes by means of threaded connections therewith.

2. The combination with a repository covered on its sides, and a boiler,of removable boxes in communication with opposite ends of saidrepository near its floor, a plurality of communicating,` detachablyunited pipes whose communicating ends ex tend into said oppositelylocated boxes, a conduit communicating between the lower part of saidboiler and the ends of said pipes adjacent thereto, a conduitcommunieating between the upper part of said boiler and the ends of saidpipes farthest therefrom, each of said pipes composed of seetions ofequal length, and couplings for said sections having separableserewthread connections therewith.

3. The combination with a repository having its sides inclosed andhavingremovable boxes in communication with opposite ends thereof, of aplurality of communicating1 pipes in said repository located near itsfloor and having their communicating ends extended into said boxes,their said ends being detachably connected, a conduitv in communicationbetween the lower part of said boiler and the adjacent ends of saidpipes, a conduit in communication between the upper part of said boilerand the ends of said pipes farthest therefrom, each of said pipes being`composed of two equal alined sections, squared couplings for said i vecents each, by addressing the "Commissioner of Patents- Washngton, D.
